摘要： A method is provided for detecting a human face in an image, such as a sequence of images supplied by a video camera. The method comprises locating in each image a candidate face region and analyzing the candidate face region for a first characteristic indicative of a facial feature. The locating step may comprise detecting uniformity saturated regions of predetermined shape in a reduced resolution version of the image. The analyzing step may comprise selecting a signal color component, forming a vertical integral projection profile and detecting an omega shape in the profile characteristic of an eye region of a face.

摘要： A method of detecting a face-like region of a colour image, comprises reducing the resolution of the colour image by averaging the saturation to form a reduced resolution image and searching for a region of the reduced resolution image. The searched region has, in a predetermined shape, a substantially uniform saturation which is substantially different from the saturation of the portion of the reduced resolution image surrounding the predetermined shape.

An apparatus for performing the foregoing method is disclosed.

摘要： An autostereoscopic display comprises an SLM which is controlled to provide an image display and a signal display. A parallax optic has a first portion which cooperates with the image display to form a plurality of viewing windows. A second portion of the parallax optic forms first and second images visible to an observer at alternate viewing windows so as to allow the observer to distinguish between desired orthoscopic viewing zones and undesirable viewing positions such as pseudoscopic positions.

摘要： A method of generating a stereoscopic image is disclosed. The method includes defining at least two, three or more regions in a scene representing a region of interest, a near regions and/or a far region. This is followed by forming an image pair for each region, this image pair containing the information relating to objects in or partially in their respective region. The perceived depth within the regions is altered to provide the idea or best perceived depth within the region of interest and acceptable or more compressed perceived depths in the other regions. The image pairs are then mapped together to form a display image pair for viewing on a display device.
